К раствору 22,4 г (93 ммоль) 2-метокси- карбонилбензолсульфонилизоцианата в 100 мл дихлорметана добавл ют 10,7 г (69,9 ммоль) 2-метокси-4-метил-6-метиламино- 1,3,5-триазина и каталитическое количество 1,4-диаза (2,2,2)бициклооктана. Реакционную смесь перемешивают в токе азота при температуре окружающей среды в течениеTo a solution of 22.4 g (93 mmol) of 2-methoxycarbonylbenzenesulfonyl isocyanate in 100 ml of dichloromethane was added 10.7 g (69.9 mmol) of 2-methoxy-4-methyl-6-methylamino-1,3,5-triazine and a catalytic amount of 1,4-diaza (2,2,2) bicyclooctane. The reaction mixture is stirred in a stream of nitrogen at ambient temperature for

10-12 ч, отгон ют растворитель, остаток растирают с диэтиловым эфиром, промывают хлорбутаном и получают твердое вещество с температурой плавлени  126-131°С, выход 27,8 г10-12 hours, the solvent is distilled off, the residue is triturated with diethyl ether, washed with chlorbutane and a solid with a melting point of 126-131 ° C is obtained, yield 27.8 g

Пример 2. Определение гербицид- ного действи .Example 2. Determination of herbicidal action.

Семена опытных растений высевают в подготовленную почву и непосредственно после этого почву обрабатывают раствором активного вещества в нефитотоксичном растворителе (довсходова  обработка)Seeds of experimental plants are sown in prepared soil and immediately after that the soil is treated with a solution of the active substance in a non-phytotoxic solvent (pre-emergence treatment)

При послевсходовой обработке опытные растени  выращивают в услови х теп- лииы до высоты 1-15 см и затем обрабатывают их раствором активного вещества .In post-harvest treatment, test plants are grown under conditions of heat up to a height of 1-15 cm and then treated with a solution of the active substance.

Результаты опытов представлены в табл. 1 и 2.The results of the experiments are presented in table. 1 and 2.

Пример 3. Определение скорости разложени  гербицида в почве (периода полураспада).Example 3. Determination of the rate of decomposition of a herbicide in soil (half-life).

Подготовленную почву, имеющую высокое значение рН, обрабатывают гербицидом , тщательно перемешивают и инкубируют при 30°С в течение определенного времени, После этого в почву высевают чувствительные виды растений и след т за их развитием.The prepared soil with a high pH value is treated with a herbicide, mixed thoroughly and incubated at 30 ° C for a certain time. After that, sensitive plant species are sown in the soil and followed by their development.

По второму варианту такую же почву обрабатывают тем же гербицидом в различных дозах и сразу же высевают в нее те же чувствительные растени .In the second embodiment, the same soil is treated with the same herbicide in various doses and immediately sown into it the same sensitive plants.

Оценку роста опытных растений и степень воздействи  на них гербицида провод т через 21 день. При этом определ ют содержание оставшегос  в инкубированной почве гербицида и оценивают степень воздействи  гербицида на растени  в неинкубированной почве.The growth of the test plants and the degree of exposure of the herbicide to them are evaluated after 21 days. The content of the herbicide remaining in the incubated soil is then determined and the extent of the effect of the herbicide on the plants in the non-incubated soil is evaluated.

Исход  из первоначальной концентрации гербицида в почве, его остаточного количества и числа суток инкубировани , определ ют период полураспада гербицида .Based on the initial concentration of the herbicide in the soil, its residual amount and the number of days of incubation, the half-life of the herbicide is determined.

В опыте с соединением А в почву заделывают 35 г/га гербицида и инкубирование почвы провод т в течение 10 сут.In the experiment with compound A, 35 g / ha of herbicide are embedded in the soil, and the incubation of the soil is carried out for 10 days.

В опыте с соединением В в почву заделывают л-9 г/га гербицида и инкубируют почву в течение 95 сут.In the experiment with compound B, L-9 g / ha of herbicide is embedded in the soil and the soil is incubated for 95 days.

Результаты опытов представлены в табл. 3 и А.The results of the experiments are presented in table. 3 and A.

Исход  из этих результатов, определ ют концентрацию оставшегос  в почве гербицида и период его полураспада.From these results, the concentration of the remaining herbicide in the soil and its half-life are determined.

В первом случае (соединение А) остаточна  концентраци  составл ет 7 г/га, а период полураспада около 4 сут.In the first case (compound A), the residual concentration is 7 g / ha, and the half-life is about 4 days.

Во втором случае (соединение В) остаточна  концентраци  составл ет 4 г/га, а период полураспада около 40 сут.In the second case (compound B), the residual concentration is 4 g / ha, and the half-life is about 40 days.
